| 摘 要： | 目的：测定不同浓度PABA对牙龄卟啉单胞菌胰酶样蛋白酶（TLP）活性的影响，以探讨血链球菌在龈下菌微生态平衡中的作用。方法：在1/2浓度的BH培养基中加入不同浓度的PABA和一定浊度的P.gingivalis，行常规培养。测定培养物上清液和菌细胞中TLP活性及蛋白质含量，计算TLP的比活。结果：PABA对P.gingivalis TLP的比活产生促进作用。结论：PABA影响P.gingivalis TLP的活性提示血链球菌可能对龈下菌斑的微生态平衡具调节作用。

| Abstract: | Objectives:In order to study the effect of PABA produced by Streptococcus sanguis on the microecological balance of subgingival plaque,different concentrations of PABA was applied to see if it can influence the action of trypsin-like protease (TLP).Methods:After adding different concentrations of PABA into 1/2 concentration of BHI media,anaerobic technique was applied to culture P.gingivalis.The action of TLP was assayed. Results:PABA improve the action of TLP. Conclusions:PABA that produced by Streptococcus sanguis affecting the action of TLP produced by P.gingivalis indicts that Streptococcus sanguis has regulative effect on the microecological balance of subgingival plaque. |
